Android Google Play Billing - querySkuDetailsAsync resurning empty list

Question

I have an Android project where I want to use com.android.billingclient.api version 4.0.0, which would replace an old billing library that google doesn't allow any more (com.anjlab.android.iab.v3). I've implemented the methods for a one-time purchase, but when querying the SKU Details with billingClient.querySkuDetailsAsync using the SKU string for the product, I get an empty result set. I've been assured that the SKU is correct, so I don't know where the error might be.

Also, the old implementation required to provide a license key, which isn't the case with the new library. Do I need to define it somewhere else in the app?

Here's the code where it fails:

 List<String> skuList = new ArrayList<>();
    skuList.add(SKU_ID);
    SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
    params.setSkusList(skuList).setType(SkuType.INAPP);

    final Activity v = this;

    billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {

        @Override
        public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {

Has anyone a suggestion what to do?

This is how I query the SKU details within my app. You can try to use this example and see if this works for you.

billingClient.startConnection(new BillingClientStateListener() {
            @Override
            public void onBillingSetupFinished(@NonNull BillingResult billingResult) {
                Log.d(TAG, "Connection finished");
                if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                    // The BillingClient is ready. You can query purchases here.
                    List<String> skuList = new ArrayList<> ();
                    skuList.add(ITEM_SKU_ADREMOVAL);
                    SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
                    params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);
                    billingClient.querySkuDetailsAsync(params.build(),
                            (billingResult1, skuDetailsList) -> {
                                // Process the result.
                                if (billingResult1.getResponseCode() == BillingClient.BillingResponseCode.OK && skuDetailsList != null) {
                                    for (Object skuDetailsObject : skuDetailsList) {
                                        skuDetails = (SkuDetails) skuDetailsObject;
                                        String sku = skuDetails.getSku();
                                        String price = skuDetails.getPrice();
                                        if (ITEM_SKU_ADREMOVAL.equals(sku)) {
                                            removeadsPrice = price;
                                        }
                                        else {
                                            Log.d(TAG,"Sku is null");
                                        }
                                    }
                                    Log.d(TAG, "i got response");
                                    Log.d(TAG, String.valueOf(billingResult1.getResponseCode()));
                                    Log.d(TAG, billingResult1.getDebugMessage());
                                }
                                else if (billingResult1.getResponseCode() == BillingClient.BillingResponseCode.ERROR) {
                                    Toast.makeText(MainActivity.this, "Error in completing the purchase!", Toast.LENGTH_SHORT).show();
                                }
                            });
                }
                else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.SERVICE_TIMEOUT) {
                    Toast.makeText(MainActivity.this, "Service timeout!", Toast.LENGTH_SHORT).show();
                }
                else {
                    Toast.makeText(MainActivity.this, "Failed to connect to the billing client!", Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onBillingServiceDisconnected() {
                restartConnection();
            }
        });

Getting this one working properly depends on several different factors

Have you published your app to Play Console or at least to an internal track or something?
Do you have active products or subscriptions on your Google Play Console?
Have you configured your licensed testers?

Please see the documentation for more info.
